Given numbers are 991,139,435,139
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,139,435,139 is 59920815.
Find LCM of 991,139,435,139 with Prime Factorization
| 139 | 991, 139, 435, 139 |
| 991, 1, 435, 1 |
Multiply the prime numbers at the bottom and the left side.
139 x 991 x 1 x 435 x 1 = 59920815
Therefore, the lowest common multiple of 991,139,435,139 is 59920815.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
991 x 139 x 435 x 139 = 8328993285
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
991 : 1, 991
139 : 1, 139
435 : 1, 3, 5, 15, 29, 87, 145, 435
139 : 1, 139
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,139,435,139, is 1.
Now, the common factors can be found like this.
991:991
139:139
435:3x 5x 29
139:139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
139 = 139
Therefore, the value for common factors is 139.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 8328993285/(1x139)
LCM = 8328993285/139
LCM = 59920815
Thus, we can understand that the LCM of 991,139,435,139 is 59920815.
